BIRD TRAP.

Application fil ed November 18, 1926. Serial No. 149,168.

This invention relates to a bird trap, and

, particularly to one adapted to catch English sparrows.

An important object is to provide 'a' novel construction of trap which will automatically reset itself after catching a bird,soas to thus successively catch birds and be especially useful where undesired birds areto' be caught and eliminated.

5 Another object is to provide a novel conconnection with the accom an in drawin s illustrating an operative embodiment.

In said drawings i m Figure 1 is a front elevation of .the trap,

Figure2 is a rear elevation of the trap;

Figure 3 is a longitudinalsectional view taken on the vertical plane indicated by the line 33 of Figure 1;

Figure 4 is a transverse sectional view taken on the vertical plane indicated by the line 44 of Figure 3;

Figure 5 is a transverse sectional view taken on the vertical plane indicated by the line 55 of Figure 3;

Figure 6 is a longitudinal sectional view taken on the horizontal plane indicated by the line 66 of Figure '5; and

Figure 7 is a top plan view of the trapwith the cover removed. v

Referring specifically to the drawings, the

trap embodies a suitable box or receptacle generally designatedlO which maybe made of any preferred material and usually. wood or metal. As shown the box is made of metal and at the top of its sides, has outwardly extending flanges 11. Said box is open at the top and a closure 12 is slidably applicable thereto. The closure 12 is provided with a handle 13, and its'side e ges have hook flanges 14 to engage the flanges 11. The frontwall 15 of the trap has a hook. flange 16 adapted to engage the for ward end of the closure 12 to form a stop for the latter in order that the latter will assume a proper position in closing the box.

The interior 'ofthe box is subdivided by struction wherein the trap has a ca tive I chamber in combination with a drum a apt-' a partition 18 into a catchin chamberlA and a captivechamber B. In t e chamber A a catching; drum 14 is'supported for rocking movement. 'Said drum as [shown is cylin-.

drical and has trunnions 15 formed by the ends of an axle or rod 15 which arev jour naledin bearings 16 fastened one to the wall 15 and the other to the wall 18. Said bearings are generally of U-shapein cross sec tion, openat the top and closed at their lower.ends,.so that the trunnions ma have efficient bearing and will be capable 0 'movement out of the bearings in removing the drum.

. The front wall 15 has an entrance opening for the birds as at 20 which is normally in registration with an entrance opening 21 in the drum 14, the drum being held in such.

position due to the provision of a weight. as

at 22. The captive is received in a restricted space of the drum only,,which is in-registra tion with the opening 21 and defined by a partition 21*. An escape opening'23 is provided through the other end wall of the drum and at times is adapted to register with an escape opening 24 leading into the captive chamber B. As a result of this construction, after a bird enters the drum, itperches on the axle 15 and its weight will overbalance the drum and move it to such a position that the openings 23 and 24 register 5 whereupon the bird will fly in its terror through the openings 23 and 24 into the captive chamber B, after which, as the weight of the bird is removed from the drum, the latter will be restored to the initial reset or catching position. ment of the drum to the catching and releasing positions is limited by means of a pin 25 .on receptacle 10 which extends from the bottom of the'latter into the interior of the trap and as through a slot 26 in drum 14, engagement of the pin with the respective end walls at the slot serving to limit the movement'of the drum to its two positions of catching and releasing An opening 23 may be provided in'the top of the drum to.

accommodate the fingers of the operator when applying or removing the drum.

The move- Captive birds may be released whenever desired through an opening 24. in the rear It is also to be understood that the sliding cover 12 is shown by'wayotemmple since other forms of covers may be used and for instance, in a Wooden structure,, the same may be hinged to the box.

It is to be'understood that the device is tobe made so as to represent a nestgem erallyand in this way serve to decoy birds into the same. Ifd'esired of course a perch may be provided on the wyalfl" 115. at the, opening 20 and bait be placedthere'on or within the drum.

Various changes may be resorted to provided they fall Within the spirit and scope ofthe invention.

What is claimed is 1. A trap of the class described having a catching chamber and a captive chamber, a partition between said chambers having an opening therethrough, a drum in. the catching chamber,,means pi'votally mounting said drum and forming a perch. therein, means:

maintaining said drumv normally in capturing position and in closing relation to said opening, said drum hangover-balanced by a captive so that the same may pass there-hem through, said opening into; the captive chamher, and subsequently return to catching position-,1 means to limit the movement of said drum comprising-a pin extending from the box and the drum having an elongated .siot coactizngwith the: pin, and bearings 'carried one by the partition and one by an "adjacent Wall of the box, said bearings being open at the top and closed at the bottom, and trimnions on the drum removably engaging said bearings.

"2. A trap of the. class described having a catching chamber and a captivecham her a partition between said chambers having an openingth reth-rongh a drum in tlie captive chamber, means pivot-ally mounting said d'rum,, means maintaini'n said drum normally" in capturing posi ion and in" cl'osing relation to said opening; said drumbeing over-balanced by a captive so that the same may pass therefroin through said opening into the captive chamber and sn'bsea quentl'y return to catching position, means tolimit the movement of the drum conipri'sin'g a pin extending from the box and the drum having an elongated sliot' coacting with the pin bearings carried one by the partition and one by an adjacent Walt of" the box saidbeafngs being open the' top and closed at:thebottom trunnions on. the drum-- removahlyengaging said bearings, and a displaceable closure on the trap norma ly" Preventing displacement ot' the drum rotatively to, said bearings.
